Median Nutrient Results 2010 - 2020

Project Overview

This report analyzed all DEQ stations with Total Phosphorus (TP) and Total Nitrogen (TN) samples taken from 2010 to 2020. Median values and number of samples the statistic was based on (n) are presented in the table below. You may download the data by using the ‘Copy’ or ‘Excel’ buttons. The ‘Column Visibility’ button allows you to turn columns on/off. Sorting and and filtering are available as well.

To better visualize this data, we have broken the median results into the below categories:

• Median TN < 1 mg/L is considered Low TN
• Median TN >= 1 mg/L & Median TN < 2 mg/L is considered Medium TN
• Median TN >= 2 mg/L is considered High TN
• Median TP < 0.05 mg/L is considered Low TP
• Median TP >= 0.05 mg/L & Median TN < 0.1 mg/L is considered Medium TP
• Median TP >= 0.1 mg/L is considered High TP
